To combine columns 'b' and 'c' into one column in your data frame, you can melt it. Additionally, you can create a column called 'color' to add coloring and a legend. Here is the code and output. It's important to note that I used the original dataframe for the point pl...

This can happen due to multiple reasons. However, usually you have tried to plot any other data before or you might have changed some plotting parameters using R codes such as par and mfrow. This is affecting the new plot that we want to create now....
I have a dataframe of 36 observations of 17 variables, but in this iteration of what I am doing I only need to plot column 2 (Total_Erosion) against columns 8-17. Am using the code below at the moment: for (i in 8:ncol(Bank1Variables)) { print(ggplot(data = Bank1Variables, aes...

下面是multiplot函数的具体定义,你可以把任意数量的图像名作为其参数,或者构建一个图像列表作为函数中的plotlist。 # Multiple plot function # # ggplot objects can be passed in ..., or to plotlist (as a list of ggplot objects) # - cols: Number of columns in layout # - layout: A matrix speci...
Rplot.png (之前知道coord_polar()函数可以把线型的图变成环状,但是不太清楚饼图也是用这个函数加参数调节来做的)比如柱形图加上coord_polar()函数就变成这个样子 bp + coord_polar() 1. 调节配色 p1<- bp + coord_polar("y",start=1) + labs(x="") + scale_fill_manual(values= c("red","blue"...
